IMAGING DIAGNOSIS—CANINE THORACIC MESOTHELIOMA

A 12-year-old neutered female Pembroke Welsh Corgi had a 2-month history of a progressive, productive cough nonresponsive to therapy. Mild pleural effusion, right middle lung lobe collapse, and multiple subpleural nodular lesions were detected in thoracic radiographs and computed tomography (CT) images. Histopathologic diagnosis of the pleural nodules was mesothelioma. Mesothelioma should be considered in patients where pleural masses are detected in radiographs or CT images.     

IMAGING DIAGNOSIS—SPLIT CORD MALFORMATION

The features of a calf with a split cord malformation are described. Clinically, there was severe cervicothoracic kyphoscoliosis and an interscapular dermal sinus associated with cerebrospinal fluid drainage. Using magnetic resonance imaging, complete duplication of the spinal cord at the cervical intumescence was detected. There was associated syringohydromyelia, multiple cervicothoracic vertebral malformations resulting in kyphoscoliosis and rachischisis, herniation of the cerebellar vermis, meningoencephalocele, and calvarial defects.
